### Question: What are the symptoms of Abdominal aortic aneurysm?
### Response: Aneurysms develop slowly over many years and often have no symptoms. If an aneurysm expands rapidly, tears open (ruptured aneurysm), or blood leaks along the wall of the vessel (aortic dissection), symptoms may develop suddenly. As the aneurysm grows, some symptoms may be:
Pulsating feeling near the navel Pain in the abdomen or back -- severe, sudden, persistent, or constant. The pain may radiate to the groin, buttocks, or legs. Clammy skin Nausea and vomiting Shock Rapid heart rate
